In light of the hot and humid temperatures that are expected to hit the greater Dayton area in the next few days, Kettering Health Network ER doctors urge you to take precautions against the heat.

Everyone is at risk when temperatures rise above 90 degrees but the elderly and the very young are most susceptible to heat and heat-related illnesses. Heat-related illnesses can cause serious injury and even death if unattended. Signs of heat-related illnesses include nausea, dizziness, flushed or pale skin, heavy sweating and headaches. Persons affected by heat-related illness should be moved to a cool place, given cool water to drink and ice packs or cool wet cloths should be applied to the skin.

Kettering Health Network ER doctors urge you to be careful when playing and working outside in extreme heat to avoid injuries and life-threatening illnesses.

• Dress for the heat. Wear lightweight, light-colored clothing. Light colors will reflect away some of the sun's energy. It is also a good idea to wear hats or to use an umbrella.

• Drink water. Carry water or juice with you and drink continuously even if you do not feel thirsty. Avoid alcohol and caffeine, which dehydrate the body. Avoid using salt tablets unless directed to do so by a physician.

• Eat small meals and eat more often. Avoid high-protein foods, which increase metabolic heat.

• Slow down. Avoid strenuous activity. If you must do strenuous activity, do it during the coolest part of the day, which is usually in the morning between 4 and 7 a.m.

• Stay indoors when possible. If air-conditioning is not available, stay on the lowest floor out of the sunshine. Remember that electric fans do not cool, they simply circulate the air.

• Be a good neighbor. During heat waves, check in on elderly residents in your neighborhood and those who do not have air conditioning.

If a person refuses water, vomits or loses consciousness, call 9-1-1, or visit your closest emergency center.
